What is Stomach Cancer?
Stomach cancer occurs when malignant (cancerous) cells form in the stomach lining. These cells can grow uncontrollably, forming a tumor, and can spread (metastasize) to other parts of the body. Gastric cancer is classified into different types based on the type of cells involved, with adenocarcinoma being the most common type, originating in the glandular cells of the stomach lining.
Symptoms of Stomach Cancer
Symptoms of Gastric cancer can be subtle, and they may resemble common stomach problems. Here are some simple English descriptions of symptoms to watch out for:
- Indigestion or Heartburn: Persistent discomfort or burning sensation in the stomach after eating.
- Feeling Full Quickly: Feeling full or bloated even after eating small amounts of food.
- Nausea and Vomiting: Feeling sick to your stomach and occasionally throwing up.
- Abdominal Pain: Pain or discomfort in the abdomen, especially in the upper part.
- Unexplained Weight Loss: Losing weight without trying or without changes in diet or exercise.
- Loss of Appetite: Not feeling hungry or having a reduced desire to eat.

Causes of Stomach Cancer
Several factors can increase the risk of developing stomach cancer:
- Helicobacter pylori Infection: This common bacterial infection of the stomach lining is a significant risk factor. Long-term infection can lead to chronic inflammation and increase the risk of cancer.
- Diet: Consuming a diet high in smoked, salted, or pickled foods and low in fresh fruits and vegetables can contribute to the development of cancer.
- Tobacco Use: Smoking increases the risk of Gastric cancer, particularly cancers of the upper part of the stomach near the esophagus.
- Family History: Having close relatives with gastric cancer or certain inherited genetic conditions can increase the risk.
- Certain Medical Conditions: Conditions such as chronic gastritis (long-term inflammation of the stomach), pernicious anaemia (a decrease in red blood cells due to the stomach's inability to absorb vitamin B12), and stomach polyps can also increase the risk.
Prevention of Stomach Cancer
Preventing stomach cancer involves adopting healthy habits and minimizing risk factors that can increase the likelihood of developing the disease.
- Healthy Diet: Eat a balanced diet rich in fruits and vegetables. Limit consumption of salty, smoked, and pickled foods, which may increase the risk of stomach cancer.
- Avoid Tobacco: Quit smoking and avoid exposure to secondhand smoke. Smoking is a significant risk factor.
- Manage Helicobacter pylori Infection: If diagnosed with H. pylori infection, follow medical advice for treatment. Chronic infection with this bacterium can lead to inflammation of the stomach lining and increase cancer risk.
- Limit Alcohol Consumption: Drink alcohol in moderation, as excessive alcohol consumption is linked to an increased risk of cancer.
- Maintain a Healthy Weight: Aim for a healthy weight through regular exercise and a balanced diet. Being overweight or obese may increase the risk of various cancers, including gastric cancer.
- Food Safety: Practice food safety measures to reduce the risk of stomach infections, which can sometimes lead to chronic gastritis and increase cancer risk.
- Regular Medical Check-ups: Attend regular medical check-ups and screenings, especially if you have a family history of gastric cancer or other risk factors. Early detection can improve treatment outcomes.
Diagnosing stomach cancer typically involves a series of steps to confirm the presence of cancer and determine its extent.
Diagnosis of Stomach Cancer
A thorough review of the patient’s medical history and symptoms, followed by a physical examination to assess overall health and detect any abnormalities.
A procedure where a thin, flexible tube with a camera (endoscope) is inserted through the mouth into the stomach. This allows the doctor to examine the stomach lining for any abnormal areas or tumors. During endoscopy, biopsy samples may be taken for further analysis.
Tissue samples (biopsies) taken during endoscopy are sent to a pathology laboratory for examination under a microscope. Biopsies help confirm the presence of cancer cells and determine the type and grade of gastric cancer.
Various imaging tests may be used to determine the extent of the cancer and whether it has spread to other parts of the body. These tests may include:
- CT Scan (Computed Tomography): Detailed cross-sectional images of the abdomen and chest to identify tumors and assess lymph nodes.
- PET Scan (Positron Emission Tomography): A scan that uses a radioactive tracer to detect cancer cells throughout the body.
- MRI (Magnetic Resonance Imaging): Detailed images using magnetic fields and radio waves to examine tissues and organs.
- Barium Swallow X-ray: X-ray imaging after swallowing a contrast material (barium) to highlight abnormalities in the upper gastrointestinal tract.
Blood tests may be performed to assess overall health and detect abnormalities, such as anemia or other signs of cancer.
Once cancer of stomach is diagnosed, staging determines the extent of the cancer and helps guide treatment decisions. Staging may involve additional imaging tests and examination of lymph nodes to assess whether the cancer has spread beyond the stomach.
Stages of Stomach Cancer
Stomach cancer is classified into stages based on its spread:
- Stage 0: Cancer is in the innermost lining of the stomach.
- Stage I: Cancer has grown into deeper layers but is limited to the stomach.
- Stage II: Cancer has spread to nearby lymph nodes or deeper stomach layers.
- Stage III: Cancer has spread to all layers of the stomach and nearby structures.
- Stage IV: Cancer has spread to distant parts of the body.
Myths and Facts About Stomach Cancer
Myths
- Stomach cancer is always symptomatic in its early stages.
- Only older adults are at risk of stomach cancer.
- Eating spicy food causes stomach cancer.
- Stomach cancer is always fatal.
- Stomach cancer is hereditary and cannot be prevented.
- Stomach ulcers always lead to stomach cancer.
Facts
- Stomach cancer can develop silently without noticeable symptoms in its early stages, making regular screenings crucial for early detection.
- While age is a significant risk factor, younger individuals can also develop stomach cancer, particularly if they have other risk factors like a family history or certain infections.
- Spicy foods do not directly cause stomach cancer. However, diets high in salted, smoked, or pickled foods may increase the risk.
- Early detection and advances in treatment have significantly improved survival rates for stomach cancer. Proper treatment and management can lead to positive outcomes.
- While family history can increase risk, lifestyle choices such as maintaining a healthy diet, avoiding tobacco, and managing infections like Helicobacter pylori can reduce the risk of developing stomach cancer.
- While untreated stomach ulcers can increase the risk of certain types of stomach cancer, most ulcers do not lead to cancer. Proper medical treatment and monitoring can prevent complications.
Types of Treatment for Stomach Cancer
Treatment for stomach cancer depends on several factors, including the stage of the cancer, the location of the tumor, the overall health of the patient, and their preferences.
- Gastrectomy: Surgery to remove part or all of the stomach affected by cancer. Depending on the extent of the cancer, nearby lymph nodes may also be removed.
- Endoscopic Resection: Less invasive surgery using an endoscope to remove early-stage tumors.
Use of anti-cancer drugs to kill cancer cells or prevent their growth. Chemotherapy may be given before surgery (neoadjuvant chemotherapy) to shrink the tumor, or after surgery (adjuvant chemotherapy) to kill any remaining cancer cells.
High-energy rays or particles are used to target and destroy cancer cells. Radiation therapy may be used before surgery to shrink tumors or after surgery to destroy remaining cancer cells.
Drugs that specifically target changes in cancer cells that help them grow. These therapies often have fewer side effects than chemotherapy.
Drugs that boost the body’s immune system to help fight cancer cells. Immunotherapy is a newer approach in cancer of stomach treatment and is typically used in advanced stages or when other treatments have not been effective.
Focuses on improving the quality of life for patients with advanced gastric cancer. Palliative care may involve pain management, nutritional support, and emotional support for patients and their families.
Conclusion
Stomach cancer is a serious condition that requires early detection for the best chance of successful treatment. Understanding its causes, symptoms, diagnosis, and treatment options is crucial for effective management. If you have concerns about stomach cancer, consult with a healthcare provider for proper evaluation and care.
